SPRING, Texas--(BUSINESS WIRE)--Exxon- and Mobil-branded stations across the United States now feature
an improved gasoline that enhances vehicle performance through a
proprietary additive formulation with seven key ingredients that helps
remove intake valve deposits, which leads to better gas mileage.

“The new additive formula, which is part of our suite of Fuel Technology
SynergyTM products, is a step-change innovation for our
Exxon- and Mobil-branded stations compared to our previous additive
package,” said Rob Wollard, Americas retail fuels marketing manager for
ExxonMobil Fuels, Lubricants and Specialties Marketing Company. “From
our new Speedpass+ mobile payment option to our Plenti loyalty program,
we are constantly looking for new ways to enhance our customers’
experiences and overall satisfaction with our products and services.”

The gasoline was developed at the same ExxonMobil research and
engineering labs as ExxonMobil Formula 1 racing fuels, and includes dual
detergents to clean key engine parts, such as intake valves. It has been
extensively tested to ensure optimum performance.

Synergy gasoline is available at almost 11,000 Exxon- and Mobil-branded
retail stations in the U.S. The breakthrough Synergy forecourt image has
been piloted at 50 locations in the U.S. and will be implemented
nationwide in a multi-year rollout as part of ExxonMobil’s continuous
efforts to enhance customer’s buying experiences.

ExxonMobil has built its reputation as a technology leader over many
decades through extensive testing and product evaluations. Its research
and engineering team is committed to developing enhanced fuel
formulations that will exceed customer expectations and comply with or
exceed regulatory requirements.
